Specication of Letters Patent.

Application filed December 17, 1909?' Serial No. 533,566.

To all whom it may concern:

t Be it known that l, FRANK M. BEYDLER, a citizen of the United States,residing at Ashland, in the county of Clark and State of Kansas, haveinvented certain new and useful Improvements in Flows; and I do declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to plows and particularly to that type of plowsknown as gang plows.

The objectof the invention is to provide a plow of this class which isadapted to be drawn by a traction engine or other high power device andwhich will have the plow gangs in separate pairs adapted to moveindividually whereby any inequalities in the ground are compensated forand the points kept at an even distance in the ground.

A further object of the invention is the provision of novel means forconnecting the individual gangs to the draft beam and a further objectis the provision yof means for raising and lowering the plows from theground so that the machine may readily travel from one field to theother.

Vith these and other objects in view, the invention consists of certainnovel features of construction, combination and arrangements of parts aswill be more fully described and particularly pointed out in theappended claims.

In the drawings, Figure 1 is a side elevation; Fig. 2 is a top planview; Fig. 3 is a perspective view on an enlarged scale of one of thegangs removed' from the draft beam; and Fig. 4 is an enlarged detailtransverse sectional view. Fig. 5 is an enlarged detail of thespring-carrying end of the connecting link with the bell crank shown insection.

Referring more especially to the drawings, 1 represents a draft beamwhich has centrally secured thereto a draft pole or bar 2, which isbraced to the beam by diagonals 3. This beam is constructed of heavysteel and is braced horizontally by a strain wire or rod 4 which isconnected to theunderside of the beam at each end and is held aparttherefrom by spacing struts 5. Extending rearwardly from the beam, inparallelism with the draft pole 2, are separated arms 6, to which arehingedly connected for vertical provided with a central thrust flange11,

which is adapted to bite the ground and prevent any lateral skidding ofthe plow when the gangs are partially or fully raised. vThe opposite endof the beam 1, is supported upon a easter wheel 12, which is swiveled tothe beam to have free swinging movement.

As each gang frame is similar in all respects and as they areindividually connected to the beam in numbers to suit, one only of theframes will be described specilicall Secured to the ends of the yoke 8,are plow beams 13, each comprising a pair of parallel members separatedin any suitable manner and extending rearwardly from the yoke member. Attheir rear ends, the separate beams are braced apart and held inparallelism by a bar 14 and their forward ends are braced apart by across-bar 15. At the rear ends of the beams, there are secured thedepending plow standards 16, to which the plows 17 are secured as isusual.

Extending upwardly from a suitable supporting axle 18, upon which isjournaled the supporting wheels 19, are standards 20. These standardsproject between the parallel members of the beams 13 and are bracedapart at their upper ends by a crank shaft 21, to which are connectedthe upper ends of diagonal braces 22, leading therefrom to pivotal bolts23, carried by the beams 13. These diagonal braces 22 have their upperends inside of the standards 20 and their lower ends arranged betweenthe parallel members 0f the beams 13. Similar braces 24 are pivotallysecured to the axle 18 and connected to the bolts 23. Thiseffectuallysupports the beams 13 and renders their forward extremitiessubstantially independent of the standards 20, because their forwardextremitics as will hereinafter be described, have movement upon thestandards to raise the plows from or lower them into the ground.

Keyed to the shaft 2l and normally extending laterally and rearwardlytherefrom at each end are cranks which are about seven and onehalfinches long more or less, and to which the beams 13 are connected neartheir front ends by links 2G. These links 26 are operated by two levers2*? and 30, the lever 27 being mounted to turn on the shaft 2l andhaving a pawl operating over a segmental rack 2S xed on one of thestandards 2O and the lever 30 being keyed to the shaft 2l and having apawl operating over a segmenta rack 29 rigidly secured to the lever 27for the purpose of holding the lever 30 connected with the lever 27.This lever SO is keyed to the shaft 21 and in addition to operating theplow beams also operates the crank 32 fixed on the shaft 2l for raisingor lowering the supporting shoe 83 through a connecting link S4 and abell crank lever 35. This shoe 33 has an upwardly extending` shaftconnected to the bell crank lever 85 and which travels between frictionrollers 36 preferably mounted on bracket 36 extending laterally from oneof the plow standards 1G. The rod is provided with a collar 37 locatedsome distance from the upper end of the bell crank lever and adapted toform a step for one end of a spiral spring 8S, so that inaccuracies inthe ground encountered by the shoe will not be transmitted to the crank32, or the lever 80.

It will be obvious that the segment 29 with which the pawl of lever 30is engaged, being fixed to the lever 27 which is loose on the shaft 21,and the pawl of said loose lever 27 operating over the segmental rack 28which is fixed on the standard 20, the movement of the lever 2T back andfort-h successively moves the segment 29 with it and through the pawl orlever 30 also moves said lever SO simultaneously with lever 27 andthrough the shaft 2l to which lever 30 is fixed raises and lowers theplow according to the direction of the movement of the levers. Forexample: lt will be assumed that both the leversI 2T and 30 are extendedfor iardly with the cranks 25 extendinf upwardly into substantiallyvertical position, the plows being thus held above the surface of theground in inoperative position. 'l`h-e movement of lever 30 intovertical position when the pawl thereof is released from rack 29 willcause the cranks 25 to move rearwardly and downf'ardly whereby the plows1T will be lowered about one-half the distance of which they are capableof moving and this movement will project them into the ground about oneand one-lialf inches, as shown in Fig. l. The pawl of lever 30 is thencaused to engage rack 29 and the lever 27 moved to upright positionwhich carries with it lever 30 and throws it into its extreme rearwardposition which movement of lever 30 turns the shaft 2l sufficiently tocause the cranks 25 to move downwardly into vertical position whichforces the plows into the ground about nine inches more or less, leavingthe lever 27 in upright position within easy reach of the operator forcontrolling the plows to a limited extent and for bringing the lever 3()forward when desired into easy reach of the operator.

It will thus be seen that in actual operation the depth of the plows maybe ordinarily regulated by the lever 2T after lever 2:30 has beenadjusted in operating position and the plows may be raised and loweredfor turning and the like by operation of the lever 27, but for theextreme movements of said plow the lever 30 is operated. By the use ofthese two levers the adjustment of the plows is accomplished partly byone and partly by the other. One of them is always in reach of theoperator and neither is ever brought low enough to come in contact withthe platform or main frame.

It will be noticed that by constructing a gang plow in this manner, eachseparate gang or pair of plows is individually connected to the draftbeam so that they may be individually raised or lowered and each mayaccommodate itself to the conditions.

From the foregoing description, taken in connection with theaccompanying drawings, the construction and operation of the inventionwill be readily understood without requiring a more extendedexplanation.

Various changes in the form, proportion and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of the invention, as defined in theappended claims.

Having thus described my invention, what I claim is:

l. A plow comprising a draft beam, a gang frame pivotally connectedthereto for vertical and horizontal movement and comprising an axle, apair of supporting wheels mounted thereon, standards projecting upwardlyfrom said axle, bracing mechanism secured to the standards, plow beamsfulcrumed intermediately of their ends upon said bracing means, plowsupon the beams, adjustable means for supporting the plows in elevatedposition and means for raising and lowering the beams at one end.

2. A plow comprising a draft beam, gang frames pivotally connectedthereto and composed of a pair of supporting wheels, standards extendingtherefrom, bracing` devices connected to the standards, parallel plowbeams fulcrinned upon the bracing devices, means carried by thestandards for raising and lowering the forward ends of the beams,

means for flexibly supporting theplow beams in raised position, asegmental rack carried by the beam adjusting means, and a lever foradjusting said supporting mechanism which engages said rack.

3. A plow comprising a draft beam, a gang frame pivotally connectedthereto and composed of supporting wheels, standards extending upwardlytherefrom, braces connected at one end to opposite ends of saidstandards and pivotally connected together at their other ends, plowbeams fulcrumed intermediately of their ends to the pivots which connectsaid braces and each composed of two parallel bars, said braces beingarranged between the members of said beams, the front end of said beamsbeing slidably engaged with said standards, plows depending from therear ends of said beams, means for supporting said beams in raisedposition, and means for holding said supporting means in adjustedposition.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
